AMD Ryzen 9 Threadripper Lineup Leaked – up to 16 Cores & 4.1GHz With Quad Channel DDR4 Support & 44 PCIe Lanes

May 15, 2017

AMD’s entire Ryzen 9 Threadripper CPU lineup has been leaked, featuring 16, 14, 12 and 10 core parts with clock speeds of up to 4.1GHz. The company’s brand new enthusiast CPU lineup is set to launch this June and bring the company’s outstanding Zen architecture to the high-end desktop.

The Ryzen 9 lineup, code named Threadripper, will be compatible with a modified version of the company’s SP3 socket, code named SP3r2, which was originally designed for AMD’s 32 core Naples server parts. The new high-end desktop platform is code named “Whitehaven” and brings support for quad channel DDR4 memory support and 44 PCIe lanes to hardware enthusiasts, content creators and developers.

AMD’s 16 Core Threadripper Monsters – Ryzen 9 1998X & Ryzen 9 1998

The Ryzen 9 1998X is allegedly the flagship of the new lineup, featuring 16 cores, 32 threads, a base clock speed of 3.5GHz and a boost clock speed of 3.9GHz with XFR ( Extended Frequency Range ). Amazingly, this CPU is only rated at 155W, 5 watts less than Intel’s upcoming Core i9-7920X 12 core flagship Skylake X CPU.
The Ryzen 9 1998 is the 1998X’s little brother, featuring 16 cores with slightly lower clock speeds of 3.2GHz base and 3.6GHz boost and the same 155W TDP.

14 Core Threadripper CPUs – Ryzen 9 1977X & Ryzen 9 1977

There are again two 14 core parts, the Ryzen 9 1977X is a 155W 14 core, 28 thread part with a base clock speed of 3.5GHz and a boost clock speed of 4.1GHz with XFR. The Ryzen 9 1977 features a base clock speed of 3.2GHz, a boost clock speed of 3.7GHz and a slightly lower TDP of 140W.

12 Core Threadripper CPUs – Ryzen 9 1976X,  Ryzen 9 1956X & Ryzen 9 1956

The 12 core Threadripper Ryzen 9 lineup allegedly consists of three SKUs. The Ryzen 9 1976X is a 12 core, 24 thread 140W part with a base clock speed of 3.6GHz and a boost clock speed of 4.1GHz with XFR. The Ryzen 9 1956X is a 125W part, again with 12 cores & 24 threads. It runs at a base clock speed of 3.2GHz and a boost clock speed of 3.8GHz with XFR. The entry level 12 core part is the 1956, it’s rated at 125W and runs at a base clock speed of 3.0GHz and a boost clock speed of 3.7GHz.

10 Core Threadripper CPUs – Ryzen 9 1955X,  Ryzen 9 1955

We also allegedly have two 10 core parts, both rated at 125W. The Ryzen 9 1955X runs at a base clock speed of 3.6GHz  boosts to 4.0GHz with XFR. The Ryzen 9 1955 runs at a base clock speed of 3.1GHz and a boost clock speed of 3.7GHz.

Ryzen At The High-End – Whitehaven (X390/X399) & Threadripper Take On Intel’s X299 & Skylake X

The Whitehaven platform will compete directly with Intel’s upcoming HEDT X299 platform and Skylake X CPUs. The upcoming family of Ryzen 9 enthusiast Threadripper CPUs are considerably larger than the current Ryzen lineup which is why they will not be compatible with AM4. With up to 16 cores and 32 threads Ryzen 9 chips stand to be the most powerful desktop CPUs we’ve ever seen introduced in the desktop market.

The whitehaven platform offers more I/O, storage, significantly more cores, threads and L3 Cache compared to Intel’s upcoming X299 high-end desktop platform as well as the current mainstream X370 and Z370 platforms. Ryzen has established AMD’s Zen architecture as the most power efficient x86 micro architecture to date in the mainstream. Extending that power efficiency lead to the enthusiast and prosumer ends of the market with Threadripper and Whitehaven puts AMD in a very strong competitive position.

With a 16 core part in the high-end desktop the Zen architecture is well on its way to displacing Intel’s Extreme edition processors from the performance throne that they’ve long held on to. Threadripper may be the first CPU family from AMD to win the ultimate performance crown since the aptly named “Hammer” architecture & Athlon 64 parts hammered Intel’s Extreme Editions nearly 14 years ago.

Things are getting really interesting in the CPU market for the first time in a very long while.
AMD’s new Ryzen 9 lineup and Whitehaven platform will reportedly be showcased at Computex (May 30th – June 2nd). According to sources in the upstream supply chain, the new high-end desktop offerings will launch alongside AMD’s 32 core Naples processors in June.
